Just wait for the 3080ti 1000W with decent reviews just to have plenty of overhead, you could get away with 850W if you find one cheap. also PSUs have crazy pricing right now in the US. I edit my posts a lot, Twitter is @LordStreetguru just don't ask PC questions there mostly... Spoiler What is your budget/country for your new PC? what monitor resolution/refresh rate? What games or other software do you need to run? Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

I’m not doing it myself I’m just curious. I have 1x 2080 Ti and that’s enough for me but I was wondering if, hypothetically, my 850W Corsair RM850x had the power to handle another GPU.

I frequently edit any posts you may quote; please check for anything I 'may' have added. Did you test boot it, before you built in into the case? WHY NOT...?!

You can't just base it off whether or not the PSU has enough connectors. The CX600 has four PCIe connectors, but you should not use it to power two R9 295X2s. :) Link to comment Share on other sites More sharing options...

Posted July 13, 2020 Just now, GamerBlake said: So when you say “supply 2 connectors each”, does that mean it will run 2 GPUs? It comes with three leads that supply power to graphics cards, each has two 6+2pin connectors on each. However many connectors your existing 2080ti has, you'll need as many of the leads supplied for twice the number of cards (if you get a second identical card).

Posted July 13, 2020 Depends on whether OC is in consideration, but I would err on the side of 1000 watts.
